Differences Between Residential and Commercial EV Charging juillet-25-2023

At Unimi, we strive to provide you with the most detailed and comprehensive information on electric vehicle (EV) charging stations.

Commercial EV Charging Stations

Commercial EV charging solutions, on the other hand, are designed for public and commercial use, catering to a broader audience of electric vehicle users.

These stations are strategically placed in high-traffic areas, such as shopping malls, office complexes, and public parking lots or in connections to businesses that’s supporting its employees choice in switching from fossil fuel to EV.

Let’s explore the key aspects of commercial charging stations:

Power Output and Charging Speeds

Let’s begin with power output. The power output of a charging station refers to the amount of power it can deliver to the EV. Most public charging stations come in three levels, with level 1 having the lowest power output and level 3 having the highest and we need to understand the difference between these.

The power outputs for level 1 and 2 stations range from 1.4 kW to 19 kW, while level 3, also known as DC fast charging, can range output power anywhere from 25 kW to 350 kW or more. It is essential to note that charging stations with higher power outputs are generally more expensive.

Now, let’s move on to charging speeds. Charging speed is the rate at which the EV battery can be charged. Several factors impact the charging speed, such as the car’s battery size, charging station power output, and the type of electric current (AC or DC) the station uses.

Level 1 and 2 charging stations typically use AC power, while level 3 stations use DC power. With AC charging, the charging speed is usually slower compared to DC charging. However, DC charging can charge an EV battery from 0 to 80% in under 30 minutes, making them ideal for long journeys.

While level 1 and 2 charging stations are sufficient for short-term charges, level 3 charging stations are becoming increasingly popular, mainly due to their fast charging speeds.

With level 3 stations, EV users can add approximately 75 miles to their EV’s range in just ten minutes. Thus, they are ideal for busy locations, such as highways or shopping malls, where EV users need to charge their vehicles quickly.

Another thing to keep in mind is that EVs may have different charging capabilities, which depend on the car model and battery size.

For instance, a Tesla Model S can charge at a rate of up to 250 kW, while a Nissan Leaf can only handle up to 50 kW. It is essential to note your EV’s charging capabilities to optimize the charging speed without damaging the battery.

Installation and Cost

The cost of a complete commercial charging station installation can range from $7,000 to upwards of $100,000 depending on several factors. These may include facility location, the number of charging points, required power supply, and parking space availability.

Furthermore, the cost of installation may be influenced by the electrical upgrade required for the installation and the fees charged by the utility company. It is recommended to gather quotes from multiple service providers and utility companies to compare pricing and service offerings.

Maintenance and Service

Maintenance and service for a commercial EV charging station are just as important as the installation process. You need to ensure that your charging stations are regularly maintained and serviced to maintain its efficiency and safety.

It is best for commercial customers to partner with a reliable service provider that provides on-time maintenance and repair services.

Payment Options

Commercial EV charging stations offer a variety of payment options, including credit cards, mobile apps, or radio frequency identification (RFID) cards. Credit card payment is a popular option for most users, as it is easy to use and widely accepted.

Mobile apps provide a convenient way for EV owners to locate and pay for charging stations using their smartphones. RFID cards offer a contactless payment method, which can be useful for users who prefer not to use cash or credit cards.

Accessibility Options

Commercial charging stations are usually open 24/7, making it easy for EV owners to charge their vehicles at any time. This means that stations need to be easily accessible, and conveniently located in areas where EVs are likely to be, such as shopping centers, supermarkets, and gas stations.

The location of charging stations is critical to ensuring that EV owners can easily access them. Investing in strategically placed charging stations allows for better user experience, happy customers, and repeat business for business owners.

Compatibility is key

The main purpose of commercial EV charging stations is to provide a convenient charging solution for electric vehicle owners. Therefore, it’s vital that they are compatible with most, if not all, electric vehicles.

Multi-vehicle compatibility allows drivers to recharge their vehicles no matter what make or model they own. This is especially important for businesses that operate commercial charging stations, as they don’t want to exclude potential customers because of compatibility issues.

The role of standardized charging connectors

To ensure multi-vehicle compatibility, EV manufacturers have agreed on certain standards for charging connectors. The most widely used connector in Europe is the Type 2 connector for AC and the CCS – Type 2 for DC charging, which is used by most electric vehicles in Europe.

This standardization ensures that most public EV charging stations are equipped to charge electric vehicles from different manufacturers, as long as they have the correct connector.

Compatibility challenges still exist

Although standardized connectors have helped to improve compatibility between commercial EV charging stations and electric vehicles, challenges still exist. Some newer EV models have different charging connectors or require a higher charging rate than what is currently available on most charging stations.

Therefore, commercial charging station owners need to ensure that their equipment is regularly upgraded to meet these new demands.

Benefits to businesses

Multi-vehicle compatibility not only benefits electric vehicle owners but also businesses. By providing an inclusive charging solution, businesses can attract a wider range of customers, increasing foot traffic and customer loyalty.

Moreover, businesses that operate charging stations can partner with EV manufacturers to get local incentives and provide marketing and branding opportunities. Overall, supporting the growth of electric vehicles can present more opportunities for businesses.

The future of multi-vehicle compatibility

As the number of electric vehicle models continues to grow, multi-vehicle compatibility will remain a priority for commercial EV charging station design. New charging standards are also being developed that aim to increase the charging speeds and improve compatibility with different types of electric vehicles.

Therefore, it’s important for businesses that operate commercial charging stations to stay up-to-date with new advancements in the field.
